                If you have a database created by SQLite, you can migrate
                it to a Berkeley DB database for use with the BDB SQL interface. For
                production applications, you should do this only when your
                application is shutdown. 
            </p>
      <p>
                All data and schema supported by SQLite can be migrated to a
                Berkeley DB database.
